"A vegan diet, on the other hand, seems too restrictive to me: I'd prefer to keep dairy for calcium. It's very important."

Risks: "Whilst people can survive without meat, they must nevertheless remember that it's the main source of iron in the diet and it can't be found in the same proportions in vegetables.

Those following a vegetarian diet should therefore consider taking iron supplements from time to time."
Top tip to pinch from Natalie: Vegetarians can have some delicious, balanced and creative dishes based on whole grains and vegetables. There's no need to eat meat!
